.To all whom it may concern.'

Be it lrnown that l, HOWARD l, Monnis, a citizen of the Unitedcdtates,residing at San Diego, in the county of San Diego and State ofCalifornia, have invented new and useful linproveiiients in LoomElements, of which the following is a speciiication.

rlfhis invention relates to looin elements, and more particularly tocertain elements Of that loom construction and organization disclosed inanother application for U. S. Letters Jijatent for looms, filed by ineSeptember 9, 1916, Serial Number 119,208. ln said identified applicationthe various loom ele ments of the present inventionv are described,disclosed, and claimed in association with other features of thecomplete looin construction and organization. In the present applicationclaims are to be directed at the leoni elements separately or incombination, or suoli thereof as are intimately and iininediatelyassociated and combined and inter-related, and more particularly withrelation to what is designated or described in said other identifiedapplication as the weftproducing ineens, or means for associating withthe partially-formed fabric the weft units or elements. In said otheridentiiied application a particular object of the invention is set forthas being the L rovision of a loom constructed and Organized with thecapability of producing a bias-woven fabric, "f abrio in which the warpand weft thread units are related, warp to weft, at an angularity ofapproximately 90 degrees, but more particularly are related each to theside edge or edges of the fabric at angles of less than 90 degrees; andsaid invention of said identiiie application further contemplates the Y;vision of selvage portions or units at the side edges of the bias-wovenfabric., and preferably independent' of the warp and weft unit threads,and serving, as long as associated with the warp and weft units, toprevent distortion or lengthwise stretch of the fabric. The presentinvention is not to be understood as limited to any particular conipleteorganization or construction of a loom, or any loom devised for thepurpose of turning out any particular or specific pattern or weave orOrganization of fabric, whethei bias-woven, provided with a selvage unitOi units, or Ofwhatever other design or struc-V tural entity. T hepresent invention relates Ato loom elements for providing and asso-4ciating weft units with the warp units of a fabric, irrespective of thespecific design of the fabric or Jdie inter-relation of the warp andweft units or their relation to the fabric side edges, and irrespectiveof the finish or structure of the side edge portions of the fabric. T heinvention, in addition to these facility in control, and necessitating aInini.

mum of requirement of care and attention, and of great adaptability tovarying conditions and environments of use and service, and which willbe generally superior in eficiency and serviceability.

Vlith the above and other objefts in view, the invention consists in thenovel and useful provision, formation, construction, combination,association and inter-relation of parts, .members and features, all ashereinafter described, sliown in the drawings and finally pointed out inclaims:

the showing in Fig. 6 being with respect to plurality of weft threads inthe production p of multiple weft thread units; and Y Fig. 10 is adetail fragmentary side elevation of a portion of the showing in Figs. 8and 9, upon a slightly reduced scale with re# spect to the scale of saidother figures;

Figs. 5,y 6, 7, 8 and 9 are Ylikewise all upon an enlarged scale.

Corresponding parts in allithe figures are designated by the samerefe/rence characters.

Referring with particularity'to the drawings, the improved and novelloom elements disclosed therein comprise, in the main, a shuttle-needle`A by which the weft thread or threads a is or are thrown or applied sovas to be resultantly associated with the warp thread units or thepartially-completedV vfabric (not shown); weft thread supply means Bfroi'nvwhich such weft thread or weft threads is or are furi'iished tothe shuttle-needle ii.; weft thread guide means b which may be includedwithin the weft B, and wher 'y the weft thread furnished to theshuttle-neerll is definitely determined or controlled as to amount orlength for each stroke of the shuttle-needle; temporary i iining 'meansC V'whereby the'wef't tn. threads is or are held during the formation ofa given single or multiple weft thread unit', .and for such 'time thereaer ray be desired in 'accordance w'th the pio @sion and operation -aindinter-relation of al'lthe elements' of a giveuloom includii'ig suchretaining means; operating-means D for t andV operating means 'c'slnittle-needle for Vthe tempor` ry "ociated with the retaining meansother mentioned elemen s is a table F over' which the fabric which hasreceived the weft thread units is passed to such further means fortaking off or disposing of the fabric or operating upon it as may beprovided in anyv particular construction and organization of loom.V Thistable is shown as having a surface portion f over which the work ispassed, which is curved transversely, or

arcuate, to conform to the path of the shuttle- `needle A, which islikewise shown as curved or arcuate and playing in a segmental path.

The temporary retaining means C are disposed adjacent to one end 11 ofthe table F, namely, the end next adjacent'to the path of play of theshuttle-needle A. The operating means E for the temporary retainingmeans C preferably include a rotatable shaft 12, from which the table Fmay be supported Aasby a plurality of spider arms 13 which Varmy 16oscillatory movement to cause the shuttle-needle it. to executeinsertion and withdrawal strokes, whereby the weft thread a is shot intothe suitably supplied partially completed fabric to introduce thereinand associate therewith the weft thread units. ln Fig. 1 theshuttle-needle A and its carryine arm 16 are shown in full lines in thepositions assumed at the end of the insertion stroke, and in dottedlines in the positions assumed at the end of the withdrawal stroke. Y

The tubular shaft 18 revolves upon the concentric shaft 12 by means of abushing 19 within the tubular sha ft and fast thereto; and the shaft 12revolves within a ljournal 2O which is supported at the upper end of astandard or pedestal 21. Two properly organized cams 22 and 23 are fixedupon the shaft 12, and operate respectively upon rollers and 25provided'at the i'nnerends of radial rnds Q6 i .d E27 respectively,which latter with such rollers and cams are included within theoperating meansli] for the temporary retaining means C; The rods?? playtl'irongh the or keepers 151 above mentioned. The radial arm 1G isprovided at its outer end with a suitable block 2S through an opening inwhich the shuttleneodle body :29 is passed, a vset screw' or the like80`being moun ed in the block'to hold the shuttle-needle in pos'i'tion.`The shuttlenoedle body is curved, in the construction shown in thedrawings, to conform to a true are, and its rearward or inner end,inward of the block 28, is bent laterally 29 and upwardly and laterallydeflected as at 29b to terminate in an open mouth or thread guide 29C,such body 29 being tubular throughout its entire length with theeriception of its outer or forward or leading end portion 29d, which issolid and tapered or rounded to a-point so as to more effectively passthrough the shed. of the warpthreads on the insertion stroke. Adjacentto the point or eading end 29d, the tubular shuttleneedle body 29 isprovided with a lateral eye or opening 293, which communicates with theinterior of the body 29, but only at one side, not being a throughopening. As shown in Figs. 8, 9 and l0, a plurality of such eyes oropenings 29e may be provided at the forward end of the shuttle-needlebody, for accommodation of a plurality of weft threads a 56 and theapplication thereof to t-he partially-completed fabric in the employmentofthe temporary retaining means C in plural provision. The weft thread ois furnishedto the needle A, as stated by supply means B, which serve totensionally supply such weft thread, the same comprising a standard 3lrising from a suitable weft thread ball support 32 carrying a weftthread ball or balls 33, provided in number in accordance with whether asingle or more weft thread o is or tobe supplied; a

` rocker arm 34 being mounted to oscillate at the upper end of suchstandard 31, as at 35 intermediate of its ends, one end thereof be?urged downwardly by a contractile coil spring 342s connected therewith,and the otherend thereof vbeing connectediwith an adjustable bracket35?' surrounding the standard 3l. A transverse arm 36 is connected withthe standard 31 immediately below the rocker arm 34, which latter isprovided at its end opposite that engaged by the spring 34W, with athread guide or eye 37, such transverse arm 36 likewise being providedat its outer end with a thread guide 38 for the ball 33 from whichthread is to be supplied, or with one suoli guide for each such bobbin,and from'which the thread or threads leads or lead tofthe thread guideor eye 37 at the end of the rocker arm 34e.

From such ,eye 3 7 the thread is led to and enters the thread guide 29Cat the inner deflected end ofthe shuttle-needle body, whence the threadis led through the tubular shut` tle-needle body and outwardly throughthe eye or eyes 29e to he introduced within the partially-,completedfabric and associated temporarily with the temporary retaining means C.

y The weft thread guide means 7o included generally within the weftthread supply means B comprises a curved or segmental or arcuate guideplate ,.38 mounted upon the base 3.9 of the standard 21, and ranging inan arc slightly greater. than and substantially (3o-extensive with thearc of the path of travel of the shuttle-needle body 29, and

. at one side of the same, and having at one side a radial flange 38a.namely, the .edge

reinotefrom the path of travel of the shuttlc-needle body.29. Thearrangement of the several Vfeatures is such that the weft thread guidemeans b is disposed first in order, counting toward the table F, thepath of the shuttle-needle body 29 is next iii order, the retainingmeans C are next in order, and the table F is next in order. lt resultsin the operation of the shuttle-needle and the supply means B and weftthread guide means Z), that the thread or threads a, is or are directlyfed over the curved guide 33, upon the withdrawal stroke of theshuttle-needle A, and more thread is laid upon said guide than isrequired to supply the shuttle-'needle in the insertion stroke of theshuttle-needle; so that upon the insertion stroke the rocker arm 34,depressed at the end carrying the eye 37 during thel withdrawal strokeof the needle, may rise gradually under the action of the spring 3d, andput the thread a being fed to the shuttleneedle under yielding tension,so as to prevent any distortion of the needle body 29 or prevent anyloosening or overlapping or entangling of the thread fed from the eye oreyes 29e of the shuttle-needle. Uf course upon the withdrawal stroke ofthe shuttle-needle likewise suiicient thread is supplied to and 'throughthe shuttle-needle for constituting` the respective one-half of the weftthread unit introduced within the Apartially-completed fabric upon suoliwithdrawal stroke of the shuttle-needle. Of

course the thread introduced on each stroke wovenfabricto produce amultiple weit thread unit, as indicated in Figs. 8, 9 and l0,

in which case there are an equal plurality of such retaining pins 4:0 soprovided in each i stance, in either case such retaining pin orretaining pins being mounted at the outer end of rockerl arm 4:1fulcrunied as at d2 beneath the table F., so that suoli retaining pinsmay be swung radially of the table and projected beyond the outersurface or periphery 7L' thereof, by the rods 26 and 27 respectively, ofthe operating means E of such temporary retaining means` Each rockingarm is pivotally connected as at d2a to the rod 26 or 27, and is jointedoutwardly of the respective fulcruin 4t2, as at l1-lf, which fulcruin isbetween the ends of the rocking arm, to provide an extreme outer endportion i-la which carries the pin or pins 40; and as clearly shown inFig. 3 .such subdivided or jointed end of each rocker arm 4]. is capableof adjustment as between its parts by means of an adjusting screw 4l"threaded through a projecting portion of one such subdivision of therocks arm and bearing upon a progectingportion of `the other subdivisionthereof, thus deter-` be urderstood that such features are to beprovided in the complete loom within which the loom elements of thepresent invention are incorporated, such provisions being made in thecomplete loom organization disclosed and described in said otherapplication for U. S. Letters Patent hereinabove identified. rIhe innerend portion of 29h of the shuttle-needle `body 29v is deflectedoutwardly and laterally as described so that the thread guide 29C mayoverlie the curved guide 38. rIhe iiange 38a acts to preventdisplacement of the thread from the guide 38.

is manifest that many changes and modifications and variations may bemade in adapting the invention to various conditions of use and service,and which departure may be made from the specific provision,construction, combination, association and inter-relation of parts,members and features herein shown and described all without departingfrom the spirit of the invention and a fair interpretation thereof.
